When a Qt module Foo links against a Qt module Bar then we add the
${QT_BUILD_DIR}/include/QtBar/QtBar header to the list of precompiled
header files. However, this only works if Foo and Bar are in the same
build system, e.g. in the same repository or in a top-level build. For
example, the QtCore header was never precompiled when in a per-repo
build of QtSvg.
Now, we determine whether Foo and Bar are in the same build system. If
they are, we proceed as before. Otherwise, we calculate the QtBar
header's location from the following data:
- the location of Qt6BarConfig.cmake
- the relative path to Bar's include directory
The Q*Application tests' project files had to be adjusted to use
NO_PCH_SOURCES now, because they use the source file
apphelper_plugin.cpp that specifically checks that pre-compiled headers
are not used for its compilation.

QtBuild.cmake is huge. Split it.
Move module, plugin, tools, executables and test related functions out
of QtBuild.cmake into separate files.
Do the same for many other things too.
An additional requirement is that all the new Helpers files only
define functions and macros.
No global variable definitions are allowed, nor execution of commands
with side effects.
Some notes:
qt_install_qml_files is removed because it's dead code.
Some functions still need to be figured out, because they are
interspersed and depend on various global state assignments.
